Faxes you have received are automatically archived in the Fax Console's
Inbox and faxes you have sent are archived in the Fax Console's Sent Items
Folder. You can easily access these folders from Windows Explorer. The
default location of these folders is:
<drive>:\Documents and Settings\All Users\Application Data\Microsoft\Windows
I'm suggesting you create a new archive folder (your current one may be
full), then set the Fax Console to store received faxes in the new folder.
This option is very easy to find in the Fax Console's options.
